摘要：

The stability range at room temperature of the orthorhombic phase of KNbO3 was investigated under pressure using optical observation and Raman scattering techniques. It was observed that the ferroelectric orthorhombic solid is stable up to the 9-10 GPa pressure range, where it transforms to the paraelectric cubic solid through a weakly first-order transformation.
